Installer stalls out at 81%

Hi, all. Brand new Windows 10 machine. Had CCleaner for years on my old machine. Trying to get this installed on new Dell. The .exe file downloads and when I launch it (double-click) I get a status window that rolls up to 81% complete. The window then closes and .... nothing. I've disabled my AV, tried to redownload (direct from ccleaner.com), and done a reboot. No joy. Any advice?

Does the same thing happen if you download and install the Slim Build from here? (last in list on page)

Also do a quick check that ccleaner isn't running in Taskmanager.

Had to shut my computer down due to weather. When I restarted, CCleaner miraculously finished the install. Weird, but I'll take it. Thanks for the reply!
